Which of the following is an example of work?

Correct answer: Watering plants

The direct answer is C: watering plants. Work is a purposeful activity in which a person uses time and effort to complete a task or meet a need. Watering plants has a clear purpose: it supplies water and helps plants remain healthy and grow. Step by step: plants need water; a person deliberately gives them water; the activity produces a useful result; therefore it is an example of work. Option A is wrong because merely sitting without thinking or a goal does not describe a purposeful task. Option B is wrong because wasting time has no productive aim in the example. Option C is correct because it is useful, intentional and responsible. Option D is wrong because wandering without purpose lacks a defined task or goal. The activity need not be paid employment to count as work in this broad lesson context. Memory cue: purposeful effort plus a useful result is work.
